The clock still ticking, I didn't manipulate too much not to cause any damage to mechanisms. I haven't found anything that look like it or similar on the internet. I did find clocks by manufacturer but not this particular one. Any information please help me with this one.
Measurements: L= 4" x w= 3"

Started as a general supplier for clockmakers tools and
equipment. Mauthe accepted clocks on a barter system.
As the demand for clocks grew, Mauthe started his own
manufacturing enterprise in 1876. His sons Christian and
Jacob joined the family enterprise in 1876.

In 1886 the Mauthe factory started her own spring drawing
facilities.

In 1899 a case factory was added, by 1900, 1000 employees
were on the payroll. In 1915 Mauthe added their own
sawmill and milling shop.

In 1923 the year of inflation made competition for Mauthe
tough. In 1930 2000 workers produced 45,000 clocks and
watches a week. By 1923, 60% German clocks exported to
London were Mauthe. In 1970, Mauthe struggled for survival,
in 1975 the company was in receivership and forced to close
in 1976.
